I promise nothing . Just a more stable (vibration free, and worrie free) flight.

I have read a lot of bad things about the DJI props, but only when you load that sucker up with Gimbal, FPV and cameras. The props have to spin that much faster to keep the same thrust, so the props snap at the base. Have also seen numerous vids showing that.

If you have a normal setup, just frame with either a GoPro or FPV (not together) I would reckon you are safe.

The guys have been raving over these Graupner props, so I want to see what all the fuss is about.

Ye slowflyer props aren't really suited for multirotors mainly because they do not spin "slow" as per their namesake. APC suggest a RPM limit of 65000/prop diameter (in inches), so in most cases with a 900kv + motor you will be over this limit. I can't stand to use EPP props, I can here the props straining so badly in flight, as much as my wallet doesn't like it, better quality props are the way forward.

Yep.

Still deciding between the Graupner 10x5 and the 11x5, seen a few guys fly with the 11x5 and they say it flies fine without overheating.

The reason I am thinking of going with the 11x5, is that your normal slow flyer prop has more prop area. The Gruapner looks more like a normal prop, the the surface area is less than the slow flyer.

Chatted to a few guys about the Graupner props, even on an unloaded rig the hover point changes on the throttle when using the 10x5, I think with the 11x5 that will compensate for the surface area and bring the hover point back on the throttle.
